What is the semisolid mixture of food and gastric juice in the stomach called?

• A. Bolus
• B. Chyme
• C. Pulp
• D. Mucus

Answer: (B)

Chyme is the semisolid mixture formed when ingested food is mixed with gastric juice in the stomach. After food is chewed into a bolus in the mouth, the stomach’s churning and gastric secretions—acid, enzymes like pepsin, and mucus—turn it into a thick, paste-like substance. This chyme is then gradually released into the small intestine for further digestion. Mucus serves as a protective coating and lubricant in the stomach, not the mixture itself, and pulp is not the term used for stomach contents.
